The physics' subject aims to provide the student with a broad understanding of the physical phenomena that occur around them every day and introduce them to the scientific search. The use of experiments in the teaching of the subject contributes to the understanding of these phenomena, the development of skills and critical thinking and has many…

This case study examined the characteristics of classroom discourse during physics lessons in two single-sex high school classes--a boys' vs. a girls' class. All lessons were taught by the same teacher and covered the same topics. For each class, six lessons were recorded, transcribed, and coded and the characteristics of the discussion were…

This paper presents the results of an exploratory case study that examined a veteran secondary teacher's knowledge for teaching non-routine mathematical problem-solving with digital technologies. Data was collected through the observation of a veteran mathematics teacher, in real time, solving a mathematical problem with the digital tools of his…

This study examines learners' issues in learning the preparation and qualitative analysis of salts topic from Malaysian chemistry teachers' perspectives. The researchers adopted a qualitative design and conducted semi-structured interviews with sixteen informants who have experience of teaching chemistry for more than five years. They were…

The article analyses teachers' learning on the use of multiple representations (MRs) in the teaching of Ohm's law, examining them in a lesson study, structured in 18 meetings of 2.5 hours each, that addressed this physics curricular topic for the 3rd grade of high school. The qualitative research involved four teachers who teach physics in…

Observing 17 teachers for a total of 116 hours, this paper examined whether a relationship between the beliefs of novice mathematics teachers and their classroom practices exists. A Spearman correlation analysis showed a modest relation between beliefs about the nature of mathematics and about learning mathematics, while the relationship between…

Empirical evidence has shown that children's mathematics achievement in South African has been on the low trend. However, no study has explored the practitioners' application of conceptions of mathematical knowledge in enhancing learners' achievement in mathematics. The study examined how practitioners apply mathematical knowledge to enhance early…

Very few Lebanese students have been able to perform at the highest level in mathematics and science in TIMSS, leading to the belief that current curricula and/or pedagogies are not supporting our highly able students to realize their potentials. In this research, we investigate how the national Policy documents and the mathematics and science…

Technology is recognized for its potential to implement exploration tasks. The ease and speed with which it becomes possible to observe many cases of a situation, allows the development of conjectures and brings conviction about their veracity. Mathematical proof, assumed as the essence of Mathematics, tends to appear to the students as something…

This exploratory case study aims to determine how preschool teachers' epistemological beliefs influence their pedagogical conceptualizations of science teaching. The research was conducted with a total of 10 teachers that were selected among 61 preschool teachers by their epistemological beliefs. The participants were divided into two sub-groups…

This article discusses how two beginning mathematics teachers mobilize and develop their didactics knowledge, specifically concerning knowledge of statistical content and teaching practice, during a teacher education experience. This work was developed as part of a specialization course for elementary school mathematics teachers, in the subjects…

The goal of this study is to examine the role of knowledge and epistemological beliefs in the relationship between STEM (science, technology, engineering, and mathematics) professional development programme (SPDP) and instructional practices in a longitudinal study. To achieve this goal, it first determined the relationship and impact of SPDP on…

The purpose of this study is to identify the teaching styles and problems faced by teachers as they attempt to cultivate higher-order thinking skills (HOTS) in the topic of quadratic equations. This study used a qualitative approach via structured interview involving four participants who are experienced mathematics teachers from three districts…

The M@t.abel2020 project supported Italian teachers during the COVID-19 pandemic period, proposing activities based on the mathematics laboratory teaching method which are suitable for distance learning situations. The project resulted in the establishment of an online community of 1,500 teachers. In this paper we present an exploratory study…

In order to thrive in today's uncertain environment, there is a need to master 21st century skills as well as knowledge of key subjects. Project-based learning (PBL) has been recommended as an important instructional strategy to prepare students for their future work and life. As teachers play an important role in classroom instructional practice,…
